Serena Williams Flaunts Killer Curves in Fitness Magazine

The tennis champ is gracing the cover of the May issue of Fitness magazine, where she's showing off her rock hard abs in a red monokini.

While the brunette beauty clearly is confident with her athletic body, she hasn't always loved her strong physique.

"When I was young, I thought I should be built more like an athlete, long and lean, not with a womanly figure," Serena tells the mag. She explains that fans later complimented her body, which gave her the motivation to be more confident. "That was really motivating," she says, adding, "So I learned to be proud of my curves and embrace my large boobs."

"It's all about loving who you are and realizing that you're beautiful," she declares.

The 32-year-old athlete maintains her fit figure by playing a variety of sports, not just tennis. "I ran, and then I biked, then I did elliptical, I tried yoga," she explains. She even tried dancing!

Well, her workout routine is definitely keeping her in shape!
